Code rate
text:
In telecommunication and information theory, the code rate of a forward error correction code is the proportion of the data-stream that is useful (non-redundant). That is, if the code rate is k / n for every k bits of useful information, the coder generates a total of n bits of data, of which n − k are redundant. If R is the gross bit rate or data signalling rate, the net bit rate is ≤ R ⋅ k / n . For example: The code rate of a convolutional code will typically be 1⁄2, 2⁄3, 3⁄4, 5⁄6, 7⁄8, etc.,
